Savage 9 twist barrels will in fact stabilize a 75gr HPBT (I shoot to 650yds with these), and will also stabilize a 75gr Berger VLD, but I'm specifically curious about the performance of the 75gr A-Max.

Trying to eek every last bit if wind drift advantage I can without swapping to a 7 or 8 twist barrel and running 80s...
